"""Negative / recovery cases for the live agent battery.

Every other case file asserts the agent does the *right* thing on a clean path.
This file asserts the agent *recovers gracefully from the wrong thing*: a tool
hits a real error (missing file, no-match edit, unknown capability) and the agent
must (a) actually exercise the error path, (b) finalize with a real reply, and
(c) stay bounded — no retry loop, no over-action, no escalating a trivial miss to
durable work, no fabricating a result it never got.

Design choices for determinism (negative tests are flaky if they depend on the
model *making* the mistake):

  * We trigger errors that are **environmental and unavoidable** — the tool
    returns an error no matter how the model phrases the call (a file that does
    not exist, a string that is not present, a capability with no tool). The
    model reliably *attempts* these because it cannot pre-know the failure.
  * Recovery is scored behaviorally via the opt-in fields added to ``Case``:
    ``require_tool_error_substrings`` (proves the error path was hit),
    ``require_final_reply`` (proves it recovered + answered),
    ``max_tool_calls`` / ``max_calls_per_tool`` (proves no loop),
    ``forbid_tool_calls`` (proves no escalation to durable work for a trivial miss).

This directly guards the ratified §5 "error feedback replaces repair" invariant
and the over-action / batch-loop class we saw under load — with live evidence
rather than faith.
